Nigerians discuss the postponement of the national voting day around a news vendor on Feb. 16, 2016, in Lagos. The Independent National Electoral Commission (INEC) announced early on the morning of February 16 that the national election has been postponed till February 23, 2019.

YOLA, Nigeria — The borders were closed. Shops. universities, offices and airports too. Tens of thousands of soldiers and observers and election officials were deployed around the country. Nigerians spent their savings, and risked their lives in some cases, to travel back to their hometowns to vote. And when they went to sleep on the eve of election day, everything seemed to be in order for a day that was expected to reaffirm the transition to democracy in Africa’s most populous country.

The reality to which they awoke deflated much of that excitement and risked fanning the flames of unrest. At around 3 a.m., just five hours before polls opened, Nigeria’s election commission announced a postponement of the vote until next Saturday, after apparently realizing that large quantities of voting materials were not in place.

“Nobody knows what is going on,” said Muhammed Hammidu, a pepper farmer reached by phone in his home village of Pariya, near the northeastern city of Yola. “Rumors are flying like crazy.”

Both of Nigeria’s biggest political parties have condemned the delay, claiming that they were unaware of the election commission’s unpreparedness.

President Muhammadu Buhari said he was “deeply disappointed” and appealed to Nigerians to “refrain from all civil disorder and remain peaceful, patriotic and united to ensure that no force or conspiracy derail our democratic development.”

His main challenger, Atiku Abubakar, also called for calm and said he would join Buhari at a meeting on Saturday afternoon in the capital Abuja convened by the election commission to address next steps.

This year’s election is seen as a chance to shore up Nigeria’s democratic institutions, 20 years after the country formally transitioned to civilian government after decades of military rule. Many here are suspicious of Buhari’s commitment to free and fair elections and the delay has already elicited a deluge of conspiratorial theories on social media and the popular WhatsApp messaging platform.

“This dents the credibility of the election, because at best the election commission was incompetent,” said Amaka Anku, a Nigeria analyst at the Eurasia Group. “They couldn’t figure this out until 3 in the morning? Like, there are no excuses. How could they not know? That’s what everyone will be asking.”

Anku and other analysts have maintained that the likelihood of political violence is low in this election as Buhari and Abubakar are both Muslims from the same ethnic group, lessening the sense of rivalry that has driven bloodshed in the past. The delay slightly raises those fears, said Anku, but the larger concern is greatly depressed turnout.

“People have spent their money to go home this one time to vote and many won’t do the same again, especially with a postponement being announced so suddenly,” she said.

"There is a general recognition that we don't need these military-style weapons in New Zealand, so it's very easy to win cross-party support for this," said Mark Mitchell, who was defense minister in the previous, center-right government and who supports the ban initiated by the center-left-led Labour Party.
